Gu, Alex; Fassihi, Safa C.; Wessel, Lauren E.; Kahlenberg, Cynthia; Ast, Michael P.; Sculco, Peter K.; Nunley, Ryan M. Less
doi : 10.2106/JBJS.20.00218
The Journal of Bone and Joint Surgery. 103(8):660-667, April 21, 2021.
Knee arthroscopy may be performed prior to total knee arthroplasty (TKA) in patients with symptomatic degenerative knee changes that do not yet warrant TKA. The purpose of this study was to determine whether the time interval between knee arthroscopy and subsequent primary TKA is associated with increased rates of revision and certain complications following TKA.

Goudie, Ewan B.; Robinson, C. Michael
doi : 10.2106/JBJS.20.01139
The Journal of Bone and Joint Surgery. 103(8):668-680, April 21, 2021.
The prevalence of nonunion after a proximal humeral fracture (PHF) and the risk factors for its occurrence are poorly defined. We aimed to estimate the rate of nonunion in nonoperatively treated patients and to produce a clinical model for its prediction.
Practice Patterns and Pain Outcomes for Targeted Muscle Reinnervation: An Informed Approach to Targeted Muscle Reinnervation Use in the Acute Amputation Setting
Hoyt, Benjamin W.; Gibson, Jeffery A.; Potter, Benjamin K.; Souza, Jason M
doi : 10.2106/JBJS.20.01005
The Journal of Bone and Joint Surgery. 103(8):681-687, April 21, 2021.
Targeted muscle reinnervation (TMR) and regenerative peripheral nerve interface (RPNI) procedures have been shown to improve patient-reported outcomes for the treatment of symptomatic neuromas after amputation; however, the specific indications and comparative outcomes of each are unclear. The primary research questions were what complement of nerves most frequently requires secondary pain intervention after conventional amputation, whether this information can guide the focused application of TMR and RPNI to the primary amputation setting, and how the outcomes compare in both settings.
Risk Factors for Revision Surgery Following Radial Head Arthroplasty without Cement for Unreconstructible Radial Head Fractures: Minimum 3-Year Follow-up
Nolte, Philip-C.; Tross, Anna-K.; Groetzner-Schmidt, Corinna; Jung, Matthias K.; Porschke, Felix; Grützner, Paul A.; Guehring, Thorsten; Schüler, Svenja; Schnetzke, Marc Less
doi : 10.2106/JBJS.20.01231
The Journal of Bone and Joint Surgery. 103(8):688-695, April 21, 2021.
Revision rates following radial head arthroplasty (RHA) for unreconstructible radial head fractures (RHFs) differ vastly in the literature, and little is known about the risk factors that are associated with revision surgery. The purposes of this study were to assess the revision rate following RHA and to determine the associated risk factors.
Trends in Comorbidities and Complications Using ICD-9 and ICD-10 in Total Hip and Knee Arthroplasties
Ohnuma, Tetsu; Raghunathan, Karthik; Fuller, Matthew; Ellis, Alan R.; JohnBull, Eric A.; Bartz, Raquel R.; Stefan, Mihaela S.; Lindenauer, Peter K.; Horn, Maggie E.; Krishnamoorthy, Vijay
doi : 10.2106/JBJS.20.01152
The Journal of Bone and Joint Surgery. 103(8):696-704, April 21, 2021.
The transition to the new ICD-10 (International Classification of Diseases, Tenth Revision) coding system in the U.S. poses challenges to the ability to consistently and accurately measure trends in comorbidities and complications. We examined the prevalence of comorbidities and postoperative medical complications before and after the transition from ICD-9 to ICD-10 among patients who underwent primary total hip or knee arthroplasty (THA or TKA). We hypothesized that the transition to ICD-10 codes was associated with discontinuity and slope change in comorbidities and medical complications.
Finn/Orthopaedic Salvage System Distal Femoral Rotating-Hinge Megaprostheses in Oncologic Patients: Long-Term Complications, Reoperations, and Amputations
Ogura, Koichi; Yakoub, Mohamed A.; Boland, Patrick J.; Healey, John H
doi : 10.2106/JBJS.20.00696
The Journal of Bone and Joint Surgery. 103(8):705-714, April 21, 2021.
There is a lack of evidence regarding long-term outcomes of rotating-hinge knee prostheses with distal femoral replacement in a large oncologic patient series. In this study, we investigated the proportion of patients experiencing complications requiring surgery in the long term, as well as the cumulative incidence of implant removal/revision and amputation at 5, 10, 15, and 20 years through competing risk analyses.
Growth-Friendly Spine Surgery in Arthrogryposis Multiplex Congenita
Verhofste, Bram P.; Emans, John B.; Miller, Patricia E.; Birch, Craig M.; Thompson, George H.; Samdani, Amer F.; Sanchez Perez-Grueso, Francisco J.; McClung, Anna M.; Glotzbecker, Michael P.; on behalf of the Pediatric Spine Study Group* Less

The Journal of Bone and Joint Surgery. 103(8):715-726, April 21, 2021.
Arthrogryposis multiplex congenita (AMC) is a condition that describes neonates born with ?2 distinct congenital contractures. Despite spinal deformity in 3% to 69% of patients, inadequate data exist on growth-friendly instrumentation (GFI) in AMC. Our study objectives were to describe current GFI trends in children with AMC and early-onset scoliosis (EOS) and to compare long-term outcomes with a matched idiopathic EOS (IEOS) cohort to determine whether spinal rigidity or extremity contractures influenced outcomes.
Bone Marrow Aspirate Concentrate Combined with in Situ Forming Bioresorbable Gel Enhances Intervertebral Disc Regeneration in Rabbits

doi : 10.2106/JBJS.20.00606
The Journal of Bone and Joint Surgery. 103(8):e31, April 21, 2021.
The current surgical procedure of choice for intervertebral disc (IVD) herniation is discectomy, which induces postoperative IVD degeneration. Thus, cell-based therapies, as a 1-step simple procedure, are desired because of the poor capacity of IVDs for self-repair. The aim of this study was to investigate the repair efficacy of ultra-purified alginate (UPAL) gels containing bone marrow aspirate concentrate (BMAC) for the treatment of discectomy-associated IVD degeneration in rabbits.
Incidence of Osteolysis and Aseptic Loosening Following Metal-on-Highly Cross-Linked Polyethylene Hip Arthroplasty: A Systematic Review of Studies with Up to 15-Year Follow-up

doi : 10.2106/JBJS.20.01086
The Journal of Bone and Joint Surgery. 103(8):728-740, April 21, 2021.
This study compared the incidence of osteolysis, aseptic loosening, and revision following use of highly cross-linked polyethylene (HXLPE) or conventional polyethylene (CPE) at medium to long-term (>5 to 15 years) follow-up in primary total hip arthroplasty (THA). Incidences were quantified and compared with regard to age and method of implant fixation.

The burden of hand surgery in low and middle-income countries (LMICs) is immense and growing. Although outreach trips to LMICs have been increasing, there has remained a gap regarding assessment of quality of care on outreach trips. We developed quality measures to assess hand surgery outreach trips to LMICs.
